Struct FrameBuffer

#[repr(C)]
pub struct FrameBuffer { /* private fields */ }

A pixel-based framebuffer that controls the screen output.

Implementations

impl FrameBuffer

pub unsafe fn new(buffer_start: u64, info: FrameBufferInfo) -> Self

Creates a new framebuffer instance.

Safety

The given start address and info must describe a valid, accessible, and unaliased framebuffer.

pub fn buffer(&self) -> &[u8]

Returns the raw bytes of the framebuffer as slice.

pub fn buffer_mut(&mut self) -> &mut [u8]

Returns the raw bytes of the framebuffer as mutable slice.

pub fn into_buffer(self) -> &'static mut [u8]

Converts the frame buffer to a raw byte slice.

The same as buffer_mut() but takes the ownership and returns the mutable buffer with a 'static lifetime.

pub fn info(&self) -> FrameBufferInfo

Returns layout and pixel format information of the framebuffer.
